, or presumed autopolyploids
Mating systems in allopolyploids and autopolyploids
generally compliment the type of polyploidy exhibited.
Cytogenetic analyses of autopolyploids
: models and methods for triploids to octoploids.
Turfgrasses can range from apomictic to dioecious, from self-pollinated to cross-pollinated, and can have different ploidy levels, with some species being autopolyploid
, although the diversity of genetic potential increases by the development of new alleles, as has been shown in Tolmiea menziesii (Soltis & Rieseberg, 1986) and in Dactylis glomerata (Lum aret & Barrientos, 1990), an autopolyploid
has very little chance of becoming established because multivalents form during meiosis, causing partial sterility.
The strongest evidence for an autopolyploid
mode of origin of H.
, and allopolyploid species that are characteristic of the tribe were used to relate DNA content to previously reported genomic relationships.
